Serial Communication ActiveX Control

The SuperCom ActiveX (OLE/COM Control) for serial communications is a professional serial communication ActiveX that can be used to develop serial communication applications to control serial connections and attached serial devices (RS-232, RS-422, RS-485).

The SuperCom ActiveX for serial communications supports common Windows development environment (IDE, Compiler) and provides the programmer with properties, methods and the events in order to develop serial data communication applications.

The SuperCom ActiveX is also downwards compatible with the MSComm and compatible to PDQComm control and thus very easy to integrate into existing applications (see below how to replace MSComm, PDQComm or SaxComm with ease).

Using the SuperCom ActiveX for serial communications you easily write applications to control serial ports, Modem, Barcode Scanner, Scales, PLC, GPS receiver, POS, serial medical devices, serial printer etc. Develop file transfer and file server application.

With SuperCom the application can execute faster and smoother.

Time is valuable. Developing communication software with the SuperCom serial communication ActiveX is extremely easy and starts by placing the ActiveX icon on a Windows Form.

The SuperCom ActiveX also provides intelligent functions that considerably speed-up the development process and produce fast, reliable solutions avoiding delaying or blocking of your application.

No matter if data monitoring, receiving complex data packets or complex data transmission protocols, establishing connections or file transfer. It can run (without any special accord) optimized and transparently in background thus enabling the application to execute fast and smooth.

Communications Events

Applications using the SuperCom ActiveX can work event driven. The SuperCom ActiveX reports the events OnComm, OnDataPacket, OnConnect and OnFileInfo. The reported events enable the application to manage other tasks simultaneously while communications or file transfer last.

• The OnComm event reports when characters received, when communication errors occur, status lines e.g. CTS, DSR or RING change state, etc.
• The OnConnect event provides information during the setup of a connection (e.g. modem dialup).
• The OnDataPacket event informs about the status of observed data packets for instance if an observed data packet is received.
• The OnFileInfo event provides status information during the file transfer. A progress dialog and/or file transfer statistics can be updated.
• The OnPlug event observes PnP (Plug And Play) serial devices and the TCP/IP network. Based on the used SuperCom software, it reports when serial devices plugged in or get unplugged, a network failure (e.g. cable, hardware or software failure).

Enhanced Communications Events

The SuperCom Communications ActiveX reports more than 35 different communications events. The enhanced event reporting mechanism in SuperCom ActiveX enables you to receive events on any defined character (e.g. EOF(26), STX, ACK, NAK, etc).

Polling Mode

The SuperCom ActiveX also supports the polling mode of operation. This means to obtain with methods and properties the state of the status lines and to check the data flow for communication errors without the need to react on events.

No matter which mode of operation the application is using, SuperCom will always perform serial data communication on multiple ports or connections simultaneously and in background.

File Transfer

High speed file transfers tasks are very easy to accomplish. The following widely used standard protocols ZMODEM, YMODEM/BATCH, YMODEM, YMODEM-G, XMODEM-1K, XMODEM/CRC, XMODEM, KERMIT and ASCII are included. The SuperCom ZMODEM protocol includes important features like 'crash recovery', 32bit CRC and 'batch file transfer'. In fact, these protocols are running very stable since 1991.

ActiveX Technology - ActiveX API

It's the same ActiveX control shipped with other SuperCom packages too, like SuperCom for TCP/IP, SuperCom for ISDN, SuperCom 3964 Engine, SuperCom Suite, etc. The runtime license, included with each packet, enables to control to perform serial port connections, TCP/IP, ISDN using one and the same component. One library, one API! Read More.

MSComm Compatible

The SuperCom for Serial Communication ActiveX is compatible with the MSComm control and thus it's very easy to update existing applications using it. Replacing MSComm with SuperCom ActiveX is a fast and smooth operation.

Summary

Using the SuperCom ActiveX up to 255 ports / connections can be opened simultaneously within the same application.

Start as many instances of your application - no limit set.

Lengthy functions like file transfer, connecting, observing the data stream for special data packets or strings, and many other, are working in background while your application is performing other tasks. With SuperCom, Your application does not 'freeze' waiting on a lengthy function to complete.

Example 1
(The following briefly shows a simple example of the control operation using Visual Basic)

Example 2
(Setup connection)

ActiveX: Client Connection - OnConnect

See the same for TCP/IP or ISDN.

The connection setup runs completely in background. The application receives events about the progress. It does not matter which communication link it uses (Serial, TCP/IP or ISDN) it will require one common SuperCom API to use. The learning curve is extremely low with SuperCom!

A proven alternative to MSComm, PDQComm, SaxComm and other

One question we often get: 'Is it only Visual Basic 6 that can use the SuperCom ActiveX to replace MSComm?'. And the answer is: 'You can use the SuperCom ActiveX to replace the MSComm control under any compiler or development environment you are using it'.

Steps to replace MSComm with SuperCom ActiveX fast and safely

Replacing the MSComm32 control

• Remove the MSComm32 icon from the form or dialog it was placed on
• Drag and Drop the SuperCom ActiveX icon to the form or dialog
• Update the Name property of the SuperCom ActiveX from SCom1 to reflect the name used with the MSComm e.g. MSComm1
• Compile the application

How to replace PDQComm and SaxComm control

Is it possible to replace PDQComm or SaxComm also ?
It's nearly the same procedure as with the MSComm. Some rarely used functions named differently in SuperCom or use a different number of parameters. Thus a small rework may be needed to complete. PDQComm or SaxComm may also include functions or protocols that may not be included in SuperCom ActiveX. Even if you don't use them a detail check helps to better estimate the amount of rework required.
Replacing the PDQComm or SaxComm control

• Remove the PDQComm / SaxComm icon from the form or dialog it was placed on
• Drag and Drop the SuperCom ActiveX icon to the form or dialog
• Update the Name property of the SuperCom ActiveX from SCom1 to reflect the name used with the PDQComm / SaxComm e.g. Comm1
• Compile the application and locate what's missing
• If required, change function name or constant names
• If required, replace function, ..., Compile, ....
